Abstract
The present invention is a display assembly including: a display and a backlight module, the backlight module including a prism structure. The backlight module generates light rays and directs the light rays to the display for illuminating the display. The prism structure of the backlight module is configured for causing the light rays to be directed to the display and for causing substantially all of the light rays to be emitted from the display assembly via the display into a pre-determined viewing envelope (ex.—towards an eye position of a viewer of the display.
